Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, and in particular to a pitch structure component combined processing device. Background Art

[0002] In optoelectronic equipment, the middle shell plays a vital role. It is a key structural component that connects the pitch assembly and the azimuth assembly. As the hub of the turret's azimuth and pitch motion, the middle shell not only supports the movement of the entire system, but is also the component that bears the main load of the optoelectronic turret. Its design rigidity and processing accuracy are directly related to the turret's azimuth and pitch motion performance, which in turn affects the turret's stability and position tracking accuracy, and has a significant impact on the performance of the entire system.

[0003] The patent document with announcement number CN114799746B discloses an axis system processing method and an assembly method for a large-span radar turntable. The turntable can rotate along a vertical axis. Both ends of the turntable are respectively provided with elevation arms that can rotate with the two ends of the antenna array. The inner hole processing of the elevation arm includes the following steps: S1: first, the elevation arm is roughly bored and then installed at the two ends of the turntable respectively; S2: semi-finishing the elevation arms at both ends of the turntable; S3: applying a load plate to the upper ends of the two elevation arms, and performing fine processing on the inner hole of the elevation arm at one end; S4: rotating the turntable 180 degrees, and fine processing the inner hole of the elevation arm at the other end.

[0004] In order to reduce costs and improve processing accuracy while ensuring quality, the middle shell can adopt a combined processing mode. In this mode, the left and right arms can be processed independently, which is convenient for controlling the accuracy of the left and right arms and ensuring the quality of the entire middle shell. However, before processing the pitch arm, it is still necessary to accurately position the pitch arm. This process is not only time-consuming and labor-intensive, but also prone to inaccurate positioning due to human factors and machine tool errors, resulting in deviations. These deviations may affect the subsequent boring accuracy, and ultimately affect the overall assembly accuracy of the turret, and then affect the safety and stability of the entire system.

[0036] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0037] like Figures 1 to 8 As shown, a pitch structure component combined processing device of the present invention includes a machine tool 1, a clamping mechanism and a positioning mechanism.

[0038] A processing table 11 is provided on the machine tool 1, and a clamping mechanism is installed on the processing table 11, which is used to fix the support arm 6 to be processed on the processing table 11. A positioning mechanism is installed on the clamping mechanism, which is used to accurately position the support arm 6 to ensure processing accuracy. A mounting seat 12 is provided at the lower end of the processing table 11, and the processing table 11 is rotatably installed on the mounting seat 12, so that the support arm 6 clamped by the clamping mechanism can be driven to rotate synchronously through the rotation of the processing table 11 itself, so as to process both sides of the support arm 6. The mounting seat 12 is horizontally movably installed on the machine tool 1, and a feeding structure for adjusting the position of the mounting seat 12 is provided on the machine tool 1. By adjusting the position of the mounting seat 12, the position of the processing table 11 and the support arm 6 can be adjusted to achieve precise processing.

[0039] like Figure 2 and Figure 3 As shown, the feeding structure includes a guide rail 13, a sliding seat 14, a screw rod 15 and a screw rod 2 16. The guide rail 13 is fixedly arranged on the machine tool 1 along the length direction of the machine tool 1, the sliding seat 14 is slidably arranged on the guide rail 13, the screw rod 15 is rotatably arranged on the guide rail 13 along the length direction of the machine tool 1, and a motor for driving the screw rod 15 to rotate is installed on the guide rail 13, and the sliding seat 14 is threadedly engaged with the screw rod 15 along the axial direction of the screw rod 15. The screw rod 2 16 is rotatably arranged on the sliding seat 14 along the width direction of the machine tool 1, and a motor for driving the screw rod 2 16 to rotate is installed on the sliding seat 14, and the mounting seat 12 is threadedly engaged with the screw rod 2 16 along the axial direction of the screw rod 2 16. By rotating the screw rod 15, the sliding seat 14 can be driven to move along the length direction of the machine tool 1, thereby driving the mounting seat 12 and the processing table 11 to move along the length direction of the machine tool 1. Similarly, by rotating the screw rod 16, the mounting seat 12 and the processing table 11 can be driven to move along the width direction of the machine tool 1, thereby achieving precise adjustment of the position of the workpiece.

[0040] Among them, one end of the guide rail 13 is provided with a tailstock 17, and the drill bit is installed on the tailstock 17. During processing, through the program control of the numerical control system, the drill bit moves toward the workpiece in the horizontal direction to realize the boring operation.

[0041] like Figures 2 to 6 As shown, the clamping mechanism includes two clamping plates 2 arranged opposite to each other, and the two clamping plates 2 can approach or move away from each other. Each clamping plate 2 includes a sliding portion 21 and a rotating portion 22. The sliding portion 21 is slidably arranged on the processing table 11. The rotating portion 22 is circular, and a through hole 201 for a drill bit to pass through is provided at the center of the circle, allowing the drill bit to pass through for processing operations. Specifically, in order to achieve the relative movement of the two clamping plates 2, a screw rod 3 23 is rotatably provided on the upper end of the processing table 11, and a driving member 1 25 for driving the screw rod 3 23 to rotate is provided on the processing table 11. The driving member 1 25 can be a motor. The screw rod 3 23 is arranged along the length direction of the machine tool 1. The two ends of the screw rod 3 23 are respectively provided with threads with opposite rotation directions. The sliding portions 21 in the two clamping plates 2 are respectively matched with the screw rod 3 23 threads through two sections of threads, so that the two clamping plates 2 can move inward or outward at the same time, so as to achieve the clamping or loosening of the support arm 6.

[0042] Furthermore, in order to improve the stability of clamping, a sliding rod 24 is rotatably provided at the upper end of the processing table 11. The sliding rod 24 is arranged along the length direction of the machine tool 1. The sliding parts 21 in the two clamps 2 are slidably matched with the sliding rod 24 to provide additional support and guidance for the clamps 2.

[0043] like Figures 2 to 8As shown, the positioning mechanism includes a positioning assembly, and the positioning assembly includes a plurality of positioning rods 3 and an adjusting member. Preferably, four positioning rods 3 are arranged at intervals along the circumference of the through hole 201, and each positioning rod 3 penetrates the two clamping plates 2 along its own axial direction, and slides with the clamping plates 2 along the radial direction of the through hole 201. The positioning rod 3 is a telescopic structure, and its length can be adapted with the movement of the two clamping plates 2. Specifically, the rotating part 22 is provided with a plurality of slide grooves 221 for the positioning rod 3 to slide, and each slide groove 221 is arranged along the radial direction of the rotating part 22, and the positioning rod 3 can move along the slide groove 221 to adapt to the size of the support arm 6. An elastic member 31 is provided between each positioning rod 3 and the rotating part 22, and the elastic force direction of the elastic member 31 is the same as the sliding direction of the positioning rod 3, which is used to drive the positioning rod 3 to reset, and the elastic member 31 can be a spring.

[0044] Among them, the adjusting member can drive multiple positioning rods 3 to move synchronously along the slide groove 1 221 according to the size of the support arm 6. The adjusting member includes multiple arc plates 32, and the multiple arc plates 32 are arranged along the circumference of the rotating part 22. The rotating part 22 is provided with multiple slide grooves 222 for the arc plates 32 to slide, and the slide grooves 222 are arranged along the radial direction of the rotating part 22. The middle part of each arc plate 32 is connected with a slider 34, and the arc plate 32 slides with the corresponding slide groove 222 through the slider 34, so that the arc plate 32 can move along the radial direction of the rotating part 22 to achieve radial adjustment of the positioning rod 3. Specifically, each arc plate 32 is located between two adjacent positioning rods 3, and slots 321 are provided at both ends of each arc plate 32, so that the positioning rods 3 located at both ends of the arc plate 32 can slide and cooperate with the arc plate 32 through the slots 321 on the corresponding sides, respectively. This layout enables the arc plate 32 to effectively connect and drive adjacent positioning rods 3. A second elastic member 33 is disposed between each slider 34 and the rotating portion 22 . The elastic direction of the second elastic member 33 is the same as the sliding direction of the arc plate 32 , and is used to drive the arc plate 32 to reset. The third elastic member may be a spring.

[0045] Furthermore, the slider 34 can be set to a square shape, so that the slider 34 can only slide in the second slide groove 222 but cannot rotate, thereby avoiding the deflection of the arc plate 32 and ensuring the synchronization between the multiple positioning rods 3.

[0046] like Figure 4 and Figure 5As shown, in order to avoid errors in the machine tool 1 and ensure that the position of the hole to be bored on the support arm 6 is on the same axis as the drill bit, the positioning mechanism also includes a detection component. The detection component includes a plurality of laser sensors 4, which are respectively mounted on a plurality of positioning rods 3 to detect the distance between each positioning rod 3 and the drill bit. During operation, each laser sensor 4 emits a laser beam to the surface of the drill bit and receives a reflected light signal, and then calculates the distance between each laser sensor 4 and the surface of the drill bit by measuring the time difference from the emission to the reflection of the laser beam. Then, each laser sensor 4 sends the measured distance data to the control system, and the control system determines whether the distance data measured by each sensor is consistent. If the data is consistent, it means that the drill bit is at the center position of the plurality of positioning rods 3, and at this time, the drill bit corresponds to the position of the hole to be bored on the support arm 6, that is, the support arm 6 is accurately positioned. If the data is inconsistent, it means that the drill bit is not in the center position. At this time, the system can calculate the actual position of the drill bit based on the measurement value provided by the sensor and determine the deviation between it and the center position. Then the system adjusts the position of the workpiece through the feed structure based on the calculated deviation value. After the adjustment is completed, the above measurement process is repeated until the distance data measured by all laser sensors 4 are consistent, confirming that the drill bit is in the center position, and completing the precise positioning of the support arm 6.

[0047] Further, the rotating part 22 is rotatably mounted on the sliding part 21 around its own axis, and a driving structure for driving the rotating part 22 to rotate is provided on one of the sliding parts 21. The driving structure includes a gear 26, which is rotatably mounted on the sliding part 21, and a driving member 27 for driving the gear 26 to rotate is provided on the sliding part 21. A plurality of tooth-shaped structures are provided on the outer circumference of the rotating part 22, and the plurality of tooth-shaped structures are evenly arranged along the outer circumference of the rotating part 22 to form a complete circumferential gear ring 28, and the circumferential gear ring 28 is meshed with the gear 26 for transmission. Through the rotation of the rotating part 22, the plurality of positioning rods 3 and the laser sensor 4 can be rotated around the circumference of the drill bit, and at this time, the laser sensor 4 can measure the drill bit from multiple angles, so that the information on the drill bit surface can be obtained more comprehensively. At the same time, during the rotation process, the laser sensor 4 can detect the slight changes on the drill bit surface in real time, dynamically compensate for the deviation caused by the sensor's own error or the irregularity of the drill bit surface, improve the accuracy of the detection result, and thus improve the positioning accuracy.

[0048] like Figures 3 to 5As shown, in order to prevent the waste generated during the boring process from affecting the positioning mechanism, a protective structure is installed on the side of the two rotating parts 22 that are away from each other. The protective structure includes a protective cover 51 and a protective ring 52. The protective cover 51 can be detachably installed on the rotating part 22 to facilitate maintenance and inspection. The protective ring 52 is arranged at the through hole 201. One end of the protective ring 52 facing the rotating part 22 is fixedly connected to the rotating part 22, and the other end penetrates the protective cover 51 and extends outward, which not only protects the area around the through hole 201, so that the waste generated during the boring process will not fall onto the surrounding positioning mechanism, but also provides support for the protective cover 51. The positioning mechanism is located in the space formed by the protective cover 51 and the protective ring 52, which can effectively isolate the external environment and prevent the external environment from interfering with or damaging the positioning mechanism. Multiple positioning rods 3 are all set through the protective cover 51, so that the positioning mechanism can still work normally while being protected.

[0049] Furthermore, the diameter of the inner wall of the protective ring 52 gradually increases in the direction away from the rotating part 22 to form a conical structure inside the protective ring 52. This conical structure can effectively guide the waste chips generated during the boring process to slide down, prevent them from entering the protective space or accumulating inside the protective ring 52, and reduce the impact of waste chip accumulation on processing accuracy.

[0050] The working process of the processing device of the present invention is as follows: in the initial state, the distance between the two clamping plates 2 is large, providing sufficient space for the placement of the support arm 6, and each positioning rod 3 is located at the initial position, that is, each positioning rod 3 is located at one end of the slide groove 1 221 facing the through hole 201. The support arm 6 to be processed is placed upside down between the two clamping plates 2, so that the round end of the support arm 6 faces downward and the square end faces upward. At this time, the positioning rod 3 will automatically adjust according to the size of the support arm 6, and under the action of the arc plate 32, multiple positioning rods 3 will move outward along the slide groove 1 221 synchronously, and the elastic member 1 31 will be compressed until the round end of the support arm 6 can contact the positioning rod 3 below. In this process, each positioning rod 3 will be kept in contact with the outer peripheral side of the support arm 6 under the action of the elastic member 1 31, so that the support arm 6 is erected between multiple positioning rods 3. At the same time, since the multiple positioning rods 3 are arranged in a circle and the distance between each positioning rod 3 and the axis of the through hole 201 is consistent, the support arm 6 can be pushed to the center position, and the position of the hole to be bored on the support arm 6 is consistent with the axis of the through hole 201. Then, by rotating the screw rod 3 23, the two clamping plates 2 are brought closer to each other, the support arm 6 is clamped, and the initial positioning of the support arm 6 is completed.

[0051] Then, the driving structure drives the rotating part 22 to rotate, so that the multiple laser sensors 4 rotate synchronously around the drill bit. At this time, the laser sensor 4 starts to work and detects the distance between it and the drill bit, that is, the distance between each positioning rod 3 and the drill bit. When the distance values ​​detected by the multiple laser sensors 4 are consistent, it means that the drill bit is located at the center position, that is, the axis of the drill bit is consistent with the position of the hole to be bored on the support arm 6. When the detected distance values ​​are inconsistent, it means that the drill bit is not located at the center position. At this time, the position of the processing table 11 can be adjusted by the feeding structure, and then the position of the workpiece can be adjusted until the drill bit is at the center position between the multiple positioning rods 3, so that the position of the hole to be bored on the support arm 6 is consistent with the axis of the drill bit, and the precise positioning of the support arm 6 is completed. At this time, the support arm 6 can be processed by moving the drill bit. After the processing of the support arm 6 is completed, the two clamps 2 move away from each other, release the clamping of the support arm 6, and the support arm 6 is removed from between the positioning rods 3. At this time, the elastic member 1 31 will push the positioning rod 3 back to the initial position to prepare for the next positioning.

[0052] Although the embodiments of the present invention have been shown and described above, it is to be understood that the above embodiments are exemplary and are not to be construed as limitations of the present invention. A person skilled in the art may change, modify, replace and vary the above embodiments within the scope of the present invention.
